Male reproductive system and sperm morphology of Eccritotarsini plant bugs (Heteroptera: Miridae)

Zoomorphology, 2021
The reproductive system and sperm morphology provide informative (but not so usual) characters in the systematic analysis, also it is still scarce for most of the insect taxa. Miridae is the largest family of Heteroptera, moreover, lower systematic relationships are still contentious, especially for the Bryocorinae subfamily.

Quantifying the complexity of plant reproductive structures reveals a history of morphological and functional integration

Proceedings of the Royal Society B: Biological Sciences, 2023
Vascular plant reproductive structures have undoubtedly become more complex through time, evolving highly differentiated parts that interact in specialized ways. But quantifying these patterns at broad scales is challenging because lineages produce disparate reproductive structures that are often difficult to compare and homologize.

Reproductive‐Stage Heat Tolerance, Leaf Membrane Thermostability and Plant Morphology in Cowpea

Crop Science, 1999
ABSTRACTHigh night temperatures during reproductive development can reduce yields of cowpea [Vigna unguiculata (L.) Walp.]. Screening whole plants for degree of flowering and pod set in hot environments has been effective in breeding for heat tolerance, but suitable screening environments often are not available.

Convergence beyond flower morphology? Reproductive biology of hummingbird‐pollinated plants in the Brazilian Cerrado

Plant Biology, 2015
AbstractConvergent reproductive traits in non‐related plants may be the result of similar environmental conditions and/or specialised interactions with pollinators. Here, we documented the pollination and reproductive biology of Bionia coriacea (Fabaceae), Esterhazya splendida (Orobanchaceae) and Ananas ananassoides (Bromeliaceae) as case studies in ...

Diverted development of reproductive organs: A source of morphological innovation in land plants

Plant Systematics and Evolution, 1997
Recent discussions of animal development, particularly at the level of molecular genetics, have emphasized modularity, dissociation and co-option as basic principles of evolutionary developmental biology. These concepts are discussed in relation to two specific structural innovations in land plant evolution: the leaves (microphylls) of lycopsids, and ...

Differences in morphology and reproductive traits of Galerucella nymphaeae from four host plant species

Entomologia Experimentalis et Applicata, 2001
AbstractThe water lily beetle Galerucella nymphaeae L. (Coleoptera: Chrysomelidae) exploits different hosts, including Nuphar lutea Sm. and Nymphaea alba L. (both Nymphaeaceae), as well as Polygonum amphibium L. and Rumex hydrolapathum Hudson (both Polygonaceae).

Morphological, reproductive and mycobiota characters of three wild medicinal plants inhabiting Western Mediterranean coastal Land, Egypt

Feddes Repertorium, 2006
AbstractLeaf surface, pollen morphology and mycobiota as well as leaf spots have been investigated in three wild medicinal plant species [Fagonia cretica L.(Zygophyllaceae);Peganum harmalaL. (Peganaceae) andScorzonera undulataVahl (Asteraceae)] growing in Egypt.
